Abstract

Kegiatan pengabdian ini bertujuan adalah untuk mentransfer pengetahuan dan teknologi serta berbagi pengalaman, penerapan ilmu, pengalian potensi diri dan pemecahan masalah yang terjadi di dalam masyarakat, terutama dibidang pertanian. Metode kegiatan yang dilakukan dalam bentuk penyuluhan, percontohan (demplot) dan pelatihan. Monitoring dan evaluasi kegiatan dilaksanakan sebanyak dua kali, yaitu pada saat survey pendahuluan dan pada akhir kegiatan pendampingan KKN mahasiswa Unand. Berdasarkan hasil survey dan data sekunder menunjukkan bahwa lapangan usaha pertanian setiap tahun mempunyai peranan yang paling besar dalam struktur perekonomian Kabupaten Tanah Datar. Berdasarkan distribusi persentase PDRB atas dasar harga berlaku, peranan lapangan usaha pertanian terhadap pembentukan PDRB Kabupaten Tanah Datar pada Tahun 2016 adalah sebesar 32,53 persen, sedangkan tahun 2017 adalah 31,55 persen atau mengalami penurunan sebesar 0,98 persen (Anonimus, 2017b). Iklim dan cuaca Tanah Datar yang mendukung serta keadaan tanah yang subur menjadikan lapangan usaha ini sebaga tumpuan dalam peningkatan kesejahteraan masyarakat, khususnya petani. Lapangan usaha ini perlu mendapat prioritas mengingat potensi sumber daya alam yang ada lebih banyak berada di lapangan usaha pertanian. Disamping itu, peningkatan bidang agroindustri dan agrobisnis juga dapat mendukung peningkatan nilai tambah lapangan usaha industri karena lapangan usaha ini termasuk lapangan usaha yang diandalkan dalam pembangunan prekonomian Kabupaten Tanah Datar di masa mendatang. Berdasarkan potensi daerah dan kondisi masyarakat di Nagari Pariangan tersebut, maka kami terdorong untuk melakukan kegiatan penyuluhan budidaya cabai merah di Nagari Pariangan, Kecamatan Pariangan, Kabupaten Tanah Datar, Sumatera Barat. Dari hasil kegiatan penyuluhan ini terlihat bahwa adanya sambutan dan antusias masyarakat untuk meningkatkan pengetahuan baik pada tingkat keluarga atau kelompok anggota masyarakat untuk mengembangkan budidaya cabai merah serta terjadi penurunan biaya produksi tanaman cabai, dengan demikian diharapkan terjadi peningkatan pendapatan petani cabai merah di Nagari Pariangan.

Abstract

Striped flying barb (Esomus metallicus) is a freshwater fish that is belonged to family Cyprinidae and genus Esomus. This fish commonly occur in the tributaries of the Siak River branches, namely Tenayan River (Tenayan Raya District, Pekanbaru Regency) and Tapung Mati River (Bencah Kelubi Village, Tapung District, Kampar Regency), and also inhabit canals along the H.R. Subrantas street in Pekanbaru. E. metallicus is small sized fish (maximum 7.3 cm TL) and characterized by oblong and compressed body; mouth opening small, oblique and directed upward; having two pair barbels, rostral barbell reach the area behind the eye, while the maxillary barbel reach anal fin. In the lateral side of the body, there is a black band that is elongated from the upper operculum to the base of caudal fin. Dorsal and anal fins are short, they are located in the opposite side of the body, but first ray of the dorsal fin is slightly frontal than the first ray of the anal fin. Linea lateralis is incomplete. AbstrakPantau janggut (Esomus metallicus) adalah ikan air tawar yang tergolong ke dalam famili Cyprinidae dan genus Esomus. Ikan ini dijumpai di anaksungai-anaksungai Siak, yaitu: Sungai Tenayan (berada di wilayah Kecamatan, Tenayan Raya, Kota Pekanbaru) dan Sungai Tapung Mati (berada di wilayah Desa Bencah Kelubi, Kecamatan Tapung, Kabupa-ten Kampar) serta di parit-parit Kota Pekanbaru sekitar Jalan H.R.

Abstract

Seagrass bed on Karang Tirtas's coast consist of two species of seagrass namely Thalassia hemprichii and Enhalus acoroides. Thalassia hemprichii is the most dominating species with a frequency to be found about 96,3% while the frequency of Enhalus acoroides is 3,7%. Seagrass has ± 14 hektar distribution area with the pattern of distribution in group. The coverage of seagrass in Karang tirta's coastal included into poor cathegory. Meanwhile, the seagrass bed is one of the important ecosystem in the coastal area that are habitat for some other species and carbon sinc. Physical chemical factor's water of Karang Tirta's coastal area can support the growth of seagrass well except the temperature factor that is high.

Abstract

This study was conducted with the aim of summarizing papers related to the distribution of the Dolphin Spinner (Stenella longirostris) in the Indian Ocean waters that had been discovered previously. The focus of the papers is to examine the distribution of S. longirostris with survey method data collection techniques. The existence of S. longirostris in the Indian Ocean waters is characterized by low levels of predation. The appearance of S. longirostris in Indian Ocean waters is located around the shore which is rich food sources at a depth of 0 - 250m. The data obtained shows in which years the distribution points in the Indian Ocean. The results obtained indicate that S. longirostris appears in the Indian Ocean almost every year.

Abstract

AbstractSungai Pisang Bay is located south of Padang City, at this location there are various activities including Pasumpahan Island water tourism, fishing, and settlement activities. This is expected to pollute the sea and have an impact on marine biota, especially phytoplankton. The purpose of this study was to examine the quality of seawater based on the composition and structure of the phytoplankton community in the Sungai Pisang Bay, Padang City. The research was conducted using survey methods and field sampling using plankton net at three sample stations on Pasumpahan Island, Ujung and Setan Island. The result is conducted 100 species of phytoplankton were found consisting of 4 classes, namely Bacillariphyceae 66 species, Chlorophycaeae 1 species, Cyanophyceae 3 species and Dinophyceae 30 species. The phytoplankton diversity index in April ranged from 2.056-3.165 and in Mei 2.644-2.977. The phytoplankton equitability index in April ranged from 0.565-0.836 and in Mei 0.727-0.809. The phytoplankton dominance index in April ranged from 0.054-0.087 and in Mei 0.096-0.131. Physical Chemistry in good condition base on KEPMEN LH No 51/2004. It can be concluded that the condition of Sungai Pisang Bay waters is based on the presence of phytoplankton in dry conditions is good.

Abstract

Research on the genetic variation of Anguilla spp. in the waters of the West Coast of West Sumatra was carried out from February to June 2022. This study used the RAPD (random amplified polymorphic DNA) method. In this study, two Anguilla species were found, namely A. marmorata and A. bicolor bicolor. The highest heterozygosity value of A. marmorata in the Tarusan River was 0,2018, and A. bicolor bicolor in Mentawai was 0,2340. The values of gene flow (Nm) in A. marmorata and A. bicolor bicolor were 0.7592 and 1.6318. The values of genetic differentiation (GST) in A. marmorata and A. bicolor bicolor were 0.3971 and 0.2345, respectively. This shows that the value of genetic variation of A. marmorata and A. bicolor bicolor in several rivers on the west coast of West Sumatra is low.

Abstract

The existence of the Electric Steam Power Plant (ESPP) in Teluk Sirih located on the seafront will certainly have an impact on changes in environmental factors such as physical, chemical and biological factors, because the water needed for the ESPP operational process comes from sea water. Changes in the physicochemical factors of sea surface water due to ESPP activity will affect organisms in these waters, one of which is phytoplankton. Therefore, the purpose of this research is to look at changes or trends in the phytoplankton community and its relation to pollution by the physics and chemistry of the waters around the ESPP Teluk Sirih. This research was conducted from June 2019 to June 2021, sampling was carried out annually for three years. This study used a purposive sampling method and plankton sampling using a plankton net horizontally, then the samples were taken to the laboratory for identification. Sampling of water physics and chemistry was carried out in situ and ex-situ, namely by being preserved for further transport to the laboratory. The results of this study indicate the trend of phytoplankton fluctuating from the number of abundance, taxa and diversity index. This is because the physicochemical factor also fluctuates, there is one parameter above the quality standard, namely phenol whose levels are more than 0.02 mg/l. However, it can be concluded that the condition of the waters in the ESPP Teluk Sirih is still in quite good condition.
